use GrokPHP\Client\Clients\GrokClient;
use GrokPHP\Client\Config\GrokConfig;
use GrokPHP\Client\Config\ChatOptions;
use GrokPHP\Client\Enums\Model;

// Initialize the client

$client = new GrokClient($config);

// Define messages
$messages = [
    ['role' => 'system', 'content' => 'You are an AI assistant.'],
    ['role' => 'user', 'content' => 'Tell me a joke!']
];

// Call API
$options = new ChatOptions(model: Model::GROK_2, temperature: 0.7, stream: false);
$response = $client->chat($messages, $options);

echo "AI Response: " . $response['choices'][0]['message']['content'];

Defaults Used:

• Model: grok-2
• Temperature: 0.7
• Streaming: false

Vision Analysis (Image Recognition)

The Vision API allows you to send images for analysis using Grok-2-Vision models.

use GrokPHP\Client\Clients\GrokClient;
use GrokPHP\Client\Config\GrokConfig;

// Initialize the client
$config = new GrokConfig('your-api-key');
$client = new GrokClient($config);

// Use the Vision API to analyze an image
$response = $client->vision()->analyze('https://example.com/image.jpg', 'Describe this image.');

echo "Vision Response: " . $response['choices'][0]['message']['content'];

Supported Models for Vision

Model Enum	API Model Name	Description
Model::GROK_2_VISION	grok-2-vision	Base Vision Model
Model::GROK_2_VISION_LATEST	grok-2-vision-latest	Latest Vision Model
Model::GROK_2_VISION_1212	grok-2-vision-1212	Default model for image analysis

Note: If you attempt to use an unsupported model for vision, an exception will be thrown.

Advanced Configuration

use GrokPHP\Client\Clients\GrokClient;
use GrokPHP\Client\Config\GrokConfig;
use GrokPHP\Client\Config\ChatOptions;
use GrokPHP\Client\Enums\Model;

// Load API key from environment
$apiKey = getenv('GROK_API_KEY');

$config = new GrokConfig($apiKey);
$client = new GrokClient($config);

// Define messages
$messages = [
    ['role' => 'system', 'content' => 'You are a helpful assistant.'],
    ['role' => 'user', 'content' => 'How do black holes form?']
];

// Custom API settings
$options = new ChatOptions(
    model: Model::GROK_2_LATEST,
    temperature: 1.2, 
    stream: false
);

$response = $client->chat($messages, $options);
echo "AI Says: " . $response['choices'][0]['message']['content'];

Available Grok AI Models

Grok AI offers multiple models optimized for different use cases.
These models are available in the Model enum inside our package:
📄 src/Enums/Model.php

Model Enum	API Model Name	Description
Model::GROK_VISION_BETA	grok-vision-beta	Experimental vision-enabled model
Model::GROK_2_VISION	grok-2-vision	Advanced multi-modal vision model
Model::GROK_2_VISION_LATEST	grok-2-vision-latest	Latest iteration of Grok vision models
Model::GROK_2_VISION_1212	grok-2-vision-1212	Enhanced vision model with performance improvements
Model::GROK_2_1212	grok-2-1212	Optimized chat model
Model::GROK_2	grok-2	Default general-purpose Grok model
Model::GROK_2_LATEST	grok-2-latest	Latest iteration of Grok-2
Model::GROK_BETA	grok-beta	Experimental beta model

Default model used: Model::GROK_2

---

Streaming Responses

The Grok API supports streaming responses for real-time interaction.
Enable it by setting stream: true:

$options = new ChatOptions(model: Model::GROK_2, temperature: 0.7, stream: true);
$response = $client->chat($messages, $options);

Streaming can be useful for chatbots, real-time applications, and CLI assistants.

Common errors and their messages:

Error Type	HTTP Code	Message

} catch (GrokException $e) {
    echo "Error: " . $e->getMessage();
}
